Answer 2

Answer:

Percentage of numbers containing digit 3 from 1 to 99 is 19.19%

Explanation:

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

Numbers from 1-99 having 3 :

3,13,23,30,31,32,33,34,35,36,37,38,39,43,53,63,73,83,93

These are 19 numbers having 3.

Fraction = 19/99

Percentage = fraction × 100

Percentage =

$\frac{19}{99} \times 100 = \frac{1900}{99}$

Percentage of numbers = 19.19%
